Result/Calculation

Temperature: 25 °C

Apparatus: Ubbelohde viscometer (Viscometer constant 0.175 cSt/s)

 

Flow Time: (1) 682.56 sec, (2) 682.06 sec, (3) 681.41 sec; average 682.01 sec

 

Kinematic Viscosity = 0.175 × 682.01 = 119.35 cSt = 1.19E-4 m²/s

Dynamic viscosity = 119.35 cSt × 1.13 g/cm³ = 134.87 cP = 134.9 mPa*s

 

 

Conclusion

The viscosity of the test item was found to be 134.9 mPa*s at 25 °C
